Welcome message from Yury Morozov, Founder 
Meet our new blockchain-based platform project. 
Our company has been in telecom business for more than 20 years. 
Seventeen years ago we were among the first to create a platform for 
intelligent communication services, including fixed-mobile 
convergence at Allo Incognito company operating in Russia. 
 
 
 
 
 
Yury Morozov 
Founder 
For more than 18 years we have been successfully developing our 
own MVNO operator company with a client base of over 250,000 
subscribers. 
But as an MVNO operator offering its services only in limited areas, 
we are still unable to provide our clients with global roaming 
service despite many efforts. 
 
Such a project would require us to sign contracts with about many hundreds global operators, 
pay a lot of money for technological convergence, check the quality of the services provided 
(voice, data, SMS, MMS, real-time billing, signaling, etc.) and also guarantee 300,000500,000 
commitments per year. Obviously, a project of such scale demands vast material and human 
resources. 
 
To provide roaming services to our subscribers, we developed and brought into commercial 
operation a special OTA platform which makes it possible to remotely swap between mobile 
profiles of a SIM card, practically on the fly. It looks like you simply bought a new local SIM card 
and inserted it into your mobile phone. 
 
We partnered with operators that currently provide services to their subscribers in more than 80 
countries and who agreed to sell their mobile profiles on condition of paying deposits to these 
operators. In fact, we can already provide services to our clients at local rates without roaming in 
more than 80 countries. But there is a big inconvenience: buying profiles involves paying a deposit 
in each country, setting up online billing and, for many countries, completing a KYC form. 
 
What we have today: 
 Operational platform that is able to upload mobile profiles on subscribers' SIM cards; 
 Operational applet certified by one of the world's largest SIM card manufacturers, Oberthur 
Technologies (OT) and Safran Identity & Security (Morpho), which determines whether the 
subscriber is in his home or guest network. Depending on the settings, it automatically swaps the 
home mobile profile for the one newly downloaded by our platform. 
 Beta version of the messenger with a playful name - Bubbletone - but serious technological 
capabilities. The Beta version is already available in the Google Play Market and the Apple App 
Store. 
 
We chose a meaningful name: while the messenger is a full-featured working tool for users, it's 
as easy to use as blowing bubbles. We believe that this fun brand name will make our 
messenger more recognizable around the world. 
3 
 
 
 
The Bubbletone app contains more than 100 functions, each being in high demand by users. For 
our current project, the most important functions are: 
 
 Retaining your mobile number in the app during remote swapping of the SIM card profile. 
Subscribers will be able to receive incoming calls via an IP channel and also pay for local 
mobile service bundles in the visited country. 
 Using Bubbletone as the first client of a decentralized network based on blockchain technology 
(explained below), which we are developing. 
Blockchain made it possible for us to radically change the rules of the game: we simply 
eliminated roaming. 
 
Collaboration by mobile operators from different countries to make roaming possible involves 
huge expenditures on infrastructure support. In fact, the provision of services to a network 
subscriber in another network requires complex interactions between various equipment of 
the providers. 
 
Our solution will let operators cast aside most of this infrastructure because many 
requirements, such as validity, integrity and indisputability, are covered by the technology 
itself. We're not daydreamers  we know exactly which minimum data are processed by 
opera- tors during service provision and what the process looks like. In our system, the 
interaction between operators is encoded in a reliable and simple smart contract that contains 
every- thing necessary to provide roaming services. 
 
Why should someone visiting another country pay 810 times more than a local? This is 
unreasonable. Plus, the poorer the country, the more expensive the roaming. 
 
In our system we change the "push" paradigm, where operators "force" their subscribers into 
another operator's network, for "pull", where operators see the new clients themselves, securely 
identify them, and connect them to their own networks. Our smart contract is a separate 
incontestable agreement between two operators and the clients themselves that is enforced 
automatically. 
 
In short, our code chooses a suitable operator for a client that will provide that client with 
roaming or any other communication service and creates a smart contract via a single 
transaction in which each party will "sign" for each action, attaching the necessary data to the 
contract every time (data will be securely encrypted so as to be accessible only by the parties.) 
Each "signature" is written into the blockchain and can be used as a reliable source of 
information on the status of the contract. 
 
What are its benefits? 
 
 Transactions are incontestable. Operations conducted in blockchain are nearly impossible 
to fake or hide. This factor is important both for operators and their clients. 
 Data are safe. An entire blockchain is kept on many nodes within the network, in many 
copies, so the chance of data loss is extremely low. 
 The transaction error rate is minimized, as each action is controlled by a strict code on the 
operators' nodes. 
4 
 
 
 Less traffic is transmitted among operators  all interactions are now conducted via a 
decentralized p2p network. 
 Any additional code the system runs on is void of sensitive information that could be 
stolen. The only data requiring protection are the private keys of the participants. 
 Other benefits of a specific blockchain are given below. 
 
We have analyzed many blockchain platforms and found them not entirely suitable for the 
telecommunications industry, as their transaction processing speed is rather low and we don't 
want to let our clients down. 
 
Our platform of choice is Graphene, which underlies the decentralized exchange BitShares and 
such widely known projects as Steemit, Golos and EOS. Our developers promise us over 10,000 
transactions per second, though, to tell the truth, 5,000 would be enough at the start. Also, the 
first prototype of the first node has already been published on GitHub 
https://github.com/Clementvale-LTD. . 
 
With our solution, operators will be able to publish their price quotes in the blockchain network 
and automatically get connected clients. The clients will receive all the data necessary for 
connection with just a couple of transactions and the operator will securely reserve the money 
to pay for the services. The amount of unnecessary traffic and hardware that will be freed up due 
to this solution is quite striking. This isn't magic or a trick, but a new class of algorithms with 
inherent ready-to-use functions for companies providing information services. 
 
Consider the following benefits: 
1. When a SIM card is first sold, the home operator validates the client and sends encrypted 
digital proof of the client's validity into a blockchain. As a result, when the client goes to 
another country, there's no need to provide their ID to get another SIM card. 
2. Roaming operators will only need to promptly offer their services and price quotes, and the 
network will distribute this information and use it to bill clients itself. 
3. The offers will be regulated by the law of supply and demand, so technical and market share 
dominance will become less important than, for instance, the quality of service. Isn't this the 
cellular communication we always wanted? 
4. We are making communication services exponentially more affordable and are fighting 
inequality. The cost to use and support our system is significantly less than what you'll find 
with other operators today. 
5. Our system has many technological advantages (and some shortcomings, of course). For 
more information, see the project's white paper or simply ask us any questions you may have. 
5 
 
 
 
We developed a special economy for the telecom industry. We have two tokens: One of them 
is stable and equals 1 SDR used in telecommunications. We named it SDR (SDR Token). It's 
the unit of payment given to providers for their services, i.e., the price of services is 
measured in these units. Everyone needs SDR tokens, and their amount is unlimited, just like 
amount of services is unlimited. The second token is UMT. It's necessary for creating smart 
contracts, and all service providers require it. For more information on tokenomics, see our 
white paper. 
 
While our blockchain platform is still under development, we have already received several 
requests from existing business projects to transfer their business processes to our blockchain. 
They need stable tokens and a quick blockchain platform, and, like ourselves, they got tired of the 
many intermediaries that sometimes earn more than those who actually provide services and 
conduct business. So, our project to kill roaming is only the beginning.

1. Executive Summary 
 
"Blockchain in Telecom" ecosystem provides direct interaction between end-users, mobile 
operators and service-providers via smart contracts. 
This reasonable  eliminates hundreds of intermediators, dramatically reduces costs of mobile 
services (up to 10 times while going abroad), and saves years and millions of $$ on 
implementation of the old- fashioned and ineffective roaming technology. 
How it works: any mobile carrier could publish its own prepaid tariff plans ("Offers") as smart 
contracts. These Offers are visible to all other operators and their subscribers. By selecting an Offer, a 
new "Request" smart contract is created, with the Digital Identity of a subscriber and Payment 
transaction. 
 
 
 
As a result, the Offer issuer identifies the user and receives money, and starts servicing the 
subscriber directly, with local price and high quality. 
The same business process is available for any non-telecom service provider (like music, TV or cloud 
services) who is interested in distributing its own Offers among multimillion customer bases of 
mobile operators. 
The Blockchain ecosystem consists of a limited number of high performance servers ("Nodes"), 
which belong to the crypto community. It means that any crypto holder could buy a license to 
manage the Node, and start earning by processing the smart contracts. 
10 
 
 
 
The more operators and service providers are connected to the "Blockchain in Telecom" ecosystem, 
the more "smart contracts" are to be processed, the more is the revenue and value of each Node. Our 
approximated projection is 10x annual growth of Smart Contracts in the ecosystem based on 
reasonable expectations of telecom services growth and observable market data. 
We believe, what this is combined with Low Risks, because we're a proven team with 20 years' 
experience in telecom industry. During this period, multiple telecom and software development 
businesses have been created: 
a. Mobile Virtual Network Operator under brand "Allo Incognito" (250K Premium Subscribers) 
 
b. "Bubbletone" messenger with 100+ useful features. It's customized for the needs of mobile 
operators to provide additional revenue streams on voice calls and SMS from the app and other 
telecom services. Beta version is already available at App Store and Google Play. 
c. Global Mobile Data Exchange developed for mobile operators who are interested in global coverage 
services for their subscribers. Currently local prices on mobile services are already available in 80+ 
countries. We are running an ICO to gather funds mainly to provide our users with innovative and 
cross-border services and for  further development of the blockchain platform, marketing, 
expanding and sustainability of the ecosystem.

2. Glossary 
 
Regional telecom carrier (hereinafter "Carrier") - a company with the  corresponding  license,  
which is providing telecom services to its subscribers, and possess a non-dominant share of a local 
market. 
SDR (Special Drawing Rights) - a unit of accounting of the International Monetary Fund ("IMF") for 
International Settlements, which is actively used by the mobile carriers for settlement. The cost of SDR 
is calculated as a basket of market rates of five world currencies: 41.7% of the US dollar, 30.9% of 
the Euro, 10.9% of the Chinese yuan, 8.3% of the Japanese yen and 8.1% of the pound sterling. 
SDR token  a token pegged to SDR (Special Drawing Rights). This token is used as a means of 
payment for services of mobile carriers and service-providers. 
UMT token (Universal Mobile Token) - a token with a limited amount specified on the ICO. A small 
number of UMT should be put into each Smart Contract when it is created to perform transactions 
under the Smart Contract. 
 
UMT tokens can be used as a means of payment for telecommunications services on the 
Bubbletone platform. Specifically, UMT tokens can be used on a user's balance in the Bubbletone 
messenger app as payment for sending messages and making voice calls in public switched 
telephone networks. 
 
To replenish the balance in the Bubbletone app, a user can buy UMT tokens making payment with fiat 
currencies, crypto currencies or SDR tokens through the payment gateway inside the Bubbletone 
platform. Crypto currencies, fiat currencies or SDR tokens will be exchanged into UMT tokens and 
will be deposited as UMT tokens on the balance of the Bubbletone app user. 
 
Proof of Importance (POI) - a further development of Proof - of - Stake consensus in the field of 
Telecom. It is a consensus based on the net transfers: how much has been 'spent' in the  past 30 
days. 
 
SLA (Service Level Agreement) - Agreement on the level of service which represents a formal 
agreement between the customer and its supplier, containing a description of services, rights and 
obligations of the parties and, most importantly, a consistent level of quality of the service. 
12 
 
 
 
 
 
 
3. Global market for messaging, mobile traffic and roaming 
 
3.1. The volume of global mobile traffic 
The global mobile traffic may reach 19 exabytes (billions of gigabytes) per month in 2018 (Cisco 
Visual Networking Index Global Mobile Data Traffic Forecast for 2013 to 2018).The process of 
digitizing our lives is irreversible. According to research from 2015 and 2016, more than 80% of the 
population in developed countries have access to the Internet, and more than 60% of Europeans own 
smartphones, with almost constant access to the network. 
 
The expected growth in mobile traffic will be, among other things, the result of the continued 
increase in mobile Internet connections of personal devices and machine-to-machine 
connections (M2M), whose 
number will exceed 10 
billion in 2018 (Cisco: in the 
period from 2012 to 2017 
the volume of mobile traffic 
will grow 13 times). 
 
The development of these 
trends is facilitated by the 
popularity of instant 
messengers (IM). Internet 
traffic of messengers 
surpassed voice 
communications and the 
volume of SMS traffic in 
2016 for the first time. By 
the number of text 
messages, IMs will surpass 
SMS by 10+ times by 2020. 
 
 
 
3.2. Tourists consume less or no traffic because of expensive roaming 
 
There are more than 1.2 billion travels per year globally, growing by 4% annually. 
 
According to Starhome Silent Roaming research, 70% of subscribers disable data 
roaming, and just 1% of subscribers consume 80% of all traffic in roaming 
 
Our experts consider this to be a consequence of high prices. This means that there is substantial 
hidden demand for cheaper traffic from tourists. 
13 
 
 
 
 
 
3.3. There are more than 900 potential partners for Bubbletone 
Blockchain 
 
Creation of the Bubbletone Ecosystem is happening with assistance and in partnership with mobile 
carriers and service-providers around the world 
 
3.4 Potential of Bubbletone Blockchain with further development of eSIM 
technology 
 
Mobile device manufacturers have been increasingly producing equipment that only works with 
embedded SIM. Latest examples are Apple Watch Series 3, Gear S2 Classic 3G and others. Growing is the 
number of smartphones that have embedded SIM as the main connectivity component or are equipped 
with it along with the traditional SIM-cards. Smart Insights (https://www.smartinsights.net/reports) 
forecasts the sales of eSIM- enabled handsets would total 346 million to 864 million units by 2020. In the 
near future 100% of devices will be eSIM-enabled. In the IoT segment the pace of eSIM adoption is even 
higher. 
 
For embedded SIM users, the Bubbletone blockchain offers an ecosystem where new economic 
relationships can be made by connecting mobile devices to a specific network. Each user will have the 
opportunity to choose a network operator and to switch to another operator including the MNP procedure 
without the involvement of operators and retailers. This approach reduces the costs of subscriber 
acquisition, starter kits production and logistics. As a result of this change, the operators can use new 
mechanisms to reduce the price of services for local rates, as compared to selling physical SIM-cards in 
retail stores. In the coming 3 to 5 years, the Bubbletone blockchain will be able to process over 30% of all 
connections to mobile networks worldwide. To implement this process, vendors of mobile devices will just 
have to connect to Bubbletone blockchain. 
 
We are creating a non-geographic mobile profile (GMP), which is not dependent on the legal requirements 
of any specific country where mobile service is rendered. This will allow for the creation of a universal 
product operational throughout the world according to uniform rules. GMP allows registration of mobile 
devices and loading of the mobile profile of the local operator via SMS or https channel in accordance with 
eSIM standards (SGP-21), Security Mechanism for the SIM (3GPP TS 23.048), and other solutions ensuring 
secure loading of profiles to mobile devices. This gives the user the option to select the necessary network 
operator and use mobile services at local rates worldwide. 
14 
 
 
 
 
 
 
For the GMP to operate correctly, we plan to maintain the relevant telecommunications infrastructure and 
also to sign agreements with network operators throughout the world to ensure the GMP is registered in 
their networks. To accomplish this, we are going to use the infrastructure of our MVNO network. 
Agreements with operators will be signed according to the standard roaming procedure utilizing the 
existing infrastructure of transit operators (SS7,IPX/GRX). GMP will change the current process of 
connecting a mobile device to the mobile operator eliminating the involvement of retail chains and SIM 
card logistics. 
 
 
4. Value for carriers, for subscribers and for crypto community 
 
Bubbletone Blockchain will create a fair and transparent ecosystem for the telecom industry to 
substitute for current ineffective and costly roaming technology. 
 
Bubbletone Blockchain should allow: 
 
 Carriers  to cut costs and increase revenues,    
 Subscribers  to gain access to local prices worldwide instead of high roaming charges and to 
earn bonuses for activities that can be spent on communication services and other services from 
the participants of Bubbletone Blockchain,    
 Crypto-Community - to enjoy rapid growth of income.    
 
Bubbletone Blockchain, as well as other global Blockchain platforms, 
will belong to Crypto Community 
 
4.1. What is roaming and roaming agreements 
 
In the context of mobile phone networks, the word "roaming" is used when a mobile phone is used 
outside of the range of its home network and connects to another available cell network. For example: 
should subscribers travel beyond their mobile carrier networks, their cell phone would automatically 
hop onto another phone company's service, if available. 
The legal roaming business aspects negotiated between the roaming partners (mobile carriers) for 
billing of the obtained services are usually stipulated in so-called roaming agreements. The GSM 
Association broadly outlines the content of such roaming agreements in standardized form for its 
members. In order for a subscriber to be registered on a visited network, a roaming agreement needs to 
be in place between the visited network and the home network. This agreement is established after a 
series of long testing processes, various legal and financial commitments, and other cumbersome 
procedures. 
The goal of the Bubbletone Blockchain platform is to eliminate all of the above long, complex and costly 
procedures, creating a new market for thousands of telecom carriers and opening affordable mobile 
services for silent roamers. Moreover, the platform creates a synergy between the telecom business and 
service providers outside of the telecom market. 
 
 
4.2. Problems for the regional carriers 
15 
 
 
 
 
 
The technology of roaming is cumbersome, expensive and hard to implement. It bears cost on the 
integration of carriers, measured in years and millions of dollars. As a result, the roaming services 
 
market has become virtually monopolized by the major carriers, and it is closed to regional carriers. The 
latter actually lose their subscribers at a time when they are traveling abroad. 
 
 
(GSMA International Roaming explained) 
 
From the time of market entry of instant messengers all carriers began to lose a substantial part of their 
revenues on voice traffic and SMS. A project to launch its own messenger for any carrier involves 
considerable time and capital cost. In addition, messengers from carriers usually lose to popular 
messengers by their functions and prevalence. For the regional carriers, it is difficult to compete with 
large players who invest significant funds in design and marketing of new services. 
One more problem is a decreasing average revenue per user because of strong competition between 
operators. Small and medium mobile operators have limited budgets on R&D and marketing to 
implement new services in short period. As a result, they are not able to compete with large mobile 
carriers on equal terms. 
 
 
 
 
4.3. Solutions of Bubbletone Blockchain for carriers 
 
By connecting to Bubbletone Blockchain, carriers will avoid the need to enter into roaming agreements. 
Mobile carriers will be able to connect to Bubbletone Blockchain through a simple API (Application 
Programming Interface). They do not have to go through a complicated and lengthy process, as in the 
case of roaming. 
16 
 
 
 
 
 
They will also be able to provide for their subscribers a Bubbletone messenger, with integrated tariffs 
plans and customized wallpaper with their logo and colors. They will be able to provide to their 
subscribers the opportunity to keep their mobile number while traveling abroad and, additionally, save 
on roaming. Which means that the home mobile carrier will not lose revenue from incoming and 
outgoing calls, which otherwise would have gone to another operator. 
In addition, mobile carriers will be able to provide services to subscribers coming to their country with 
acquisition cost close to zero. According to our calculations, to attract a subscriber today, regional 
mobile carriers spend about 20%-30% of their LTV (Lifetime Value). 
Connection of new carriers to the Blockchain is carried out by the consensus of existing players, which 
makes the process transparent, excludes patronage, and also significantly reduces the appearance of 
scammers. 
 
4.4. Problems of subscribers 
 
Being inside their home network, the subscriber does not have the ability to quickly switch between 
carriers in case of poor-quality communication because domestic carriers do not have an effective 
national roaming mechanism. 
Traveling subscribers have to significantly overpay for services of foreign carriers because the roaming 
market is monopolized by Mobile Network Operators. 
Traveling subscribers have three alternatives for roaming, but each of them has its own disadvantages: 
 
 Local SIM card: the need to look for the point of sale to set up a local SIM card, which may be 
complicated by a possible language barrier and sometimes requires several hours; risk of losing 
the user's main SIM card; change of the user's home number.    
 Global SIM card: higher rates than local SIM cards; separate balance; change of the user's home 
number; risk of losing the user's main SIM card.     
 Wi-Fi hotspots: the need to search for an access point; permanent reconnection between 
hotspots; these points usually require a password, which disrupts the continuity of the network 
connection.    
 
 
4.5. Solutions of Bubbletone Blockchain for subscribers 
 
To avoid roaming charges and stay connected with their home number outside of their home network, 
any subscriber can set up the Bubbletone Messenger and buy a local tariff in the country they visit. The 
beta version of the Bubbletone messenger is now available for download in the App Store and Google 
Play. 
The beta version of the Bubbletone Messenger already has enhanced security and unique features: 
 
1. Audio and video calls. 
2. Group chats and SMS chats 
3. Burning messages after reading. 
4. Sending messages to the future. 
5. Sending SMS from the messenger onto GSM network. 
6. Stickers and animations. 
7. Sharing photos, videos and large files. 
8. Record voice messages with pre-listening. 
9. Request geolocation of subscriber and contacts. 
17 
 
 
 
 
 
10. One account for multiple devices with message synchronization and built-in cloud storage. 
It is already supported by the mobile carrier "Allo Incognito" and negotiations are being held with 
several other carriers. 
 
In the future, we are planning to develop new functionality for the Bubbletone messenger as a part of 
Bubbletone Blockchain: 
 
1. A technical capacity to buy a virtual number in 60 countries around the world and order 
communication packages in 100+ countries around the world, according to their local tariff 
plans 
2. The ability to enable automatic selection of the carrier by the criteria of price or quality of 
communication services 
3. Access to independent rating of mobile services provided by the carriers. Each user can estimate 
the quality with one "click" in the Bubbletone messenger, and his/her choice will be recorded 
inside the Blockchain 
4. Make P2P payments in crypto and fiat currency around the globe 
5. With a built-in voting platform based on blockchain, users can organize voting contests, business 
meetings, and give honest ratings to products and services 
6. Videoconferences with a large number of participants 
7. Hidden chats and contacts in case an unidentified person appears in front of the device. 
 
 
4.6. The crypto- 
miners problem 
 
Apart from volatile 
exchange rates, crypto- 
miners have two other 
problems. 
 
1) The constant "arms 
race" because of the 
increasing complexity of 
mining. 
 
 
 
2) The problem of the utility-value of the earned crypto currency. Most crypto assets do not yet provide 
an opportunity to buy real goods and services with them. Also, they are purely speculative. 
 
 
4.7. Solutions of Bubbletone Blockchain for miners 
 
Bubbletone Blockchain gives miners an opportunity to process smart-contracts created by mobile 
carriers and service providers, and earn reward on this business. 
18 
 
 
 
 
 
Miners in Bubbletone Blockchain will be able to engage in useful work. Instead of searching for artificial 
hashes, the crypto-miners will be processing transactions for the provision of communication services 
and other online services. 
 
Miners can earn Universal 
Mobile Tokens (UMT), which 
are required in Bubbletone 
Blockchain to be used as a 
means of payment to pay 
fees 
for processing 
the 
transaction. UMT 
is 
a 
universal token to make a 
smart contract executable in 
Bubbletone 
Blockchain. 
When we connect new 
carriers and subscribers to 
the system, the number of 
transactions will grow. 
For mining in the system, 
Proof of Importance (POI) 
consensus will be used. It's 
a further development of 
"Proof 
- of  Stake" 
consensus in the field of 
Telecom. 
In order to start processing 
the transactions, crypto- 
miner should buy UMT and 
put them onto deposit. 
There are two contribution 
levels 
in 
Bubbletone 
Blockchain: 
Level 1 -  a  Super  Node    
a high-performance server which has to be switched online and tuned according to SLA (Service 
Level Agreement) to execute the Smart Contracts. It will require a deposit of 
1 million UMT. In addition to commission fee on transactions, a Super Node holder will be able to  
receive a share from the daily payment from the Network Development Fund (NDF). The purpose of 
NDF is to support the nodes until there will be enough transactions for them to process with profit. So, 
we plan to develop the network in two years. 
Level 2  a Mini Node  any computing device (even smartphone) to assist the Super Nodes in 
transaction processing. It will require a deposit of 1,000 UMT. Each Mini Node must be attached to a 
Super Node of his choice. Super Nodes will be able to give tasks to Mini Nodes such as validating of 
smart contracts. 
 
The commission fee on transaction processing will be distributed as follows: 
 
 45% goes to Super Nodes. Out of these Super Nodes may provide additional bonuses to the Mini 
Nodes attached to them. 
 30% of income is split among Mini Nodes attached to a Super Node. This Bonus can be earned by 
assistance the Super Node in transaction processing. 
 25% goes to the Community Development Fund to ensure constant development of the system 
and to exclude the Deadlock situation, where there may be not enough UMT to perform the 
transactions. 
19 
 
 
 
 
 
 
 
4.8. Proof-of-Importance (POI) consensus 
 
Proof-of-Importance is a Blockchain consensus mechanism introduced by NEM. Bubbletone Blockchain 
uses its version modified for the telecom services. 
It functions similarly to Proof-of-Stake: nodes need to 'vest' an amount of currency to be eligible for 
creating blocks and are selected for processing a transaction roughly in proportion to some score. In 
Proof-of-Stake, this 'score' is one's total vested amount, but in Proof-of-Importance, this score includes 
more variables. The calculations follow from the math of network clustering and page ranking. 
For a user who owns a Mini Node, the primary inputs of his POI rating are: 
 
1) Amount of currency in deposits for purposes of creating a node (minimum 1000 UMT) 
2) Activity in traffic consumption  this type of measurement is better than measuring outbound traffic 
as it guards against bots and spammers who could increase their rating by artificial means. 
3) Activity in transaction generation  e.g. ordering services in the past 30 days, with more recent 
transactions weighted more heavily. 
The importance rating addresses primary criticism of proof-of-stake that people simply hoard as many 
coins as possible and reap the rewards from that. This concentrates wealth while discouraging 
transactions. The importance rating means that spreading tokens around will increase it. 
For a user who owns a Super Node, the primary inputs of his POI rating are: 
 
1) Number of days from the past 100 days, when Super Node was online and performed at the level 
required by SLA. 
2) Super Node standing in the list of best performing Super Nodes in the network. 
 
 
 
5. How it works? 
 
Initially, any mobile carrier could publish its own prepaid tariff plans ("Offers") as smart contracts. 
These Offers are visible to all other operators and their subscribers. By selecting an Offer, a new 
"Request" smart contract is created, with the Digital Identity of a subscriber and payment transaction 
in SDR tokens. Each transaction has UMT to be processed by Super Nodes. 
As a result, the Offer issuer identifies the user and receives money, and starts servicing the 
subscriber directly, with local price and high quality. 
The same business process is available for any non-telecom service provider (like music, TV or cloud 
services) who is interested in distributing its own Offers among multimillion customer bases of mobile 
operators. 
The process of creating and executing of smart contracts is seamless for customers and takes about a 
minute. Direct connection to a local operator provides low rates and high LTE quality, with easy 
management using Bubbletone mobile app. 
 
We're planning to issue Global Mobile Profile in 2019 to make mobile devices connected. This profile 
will be embedded into devices by vendors, so any end-user will be able to select required mobile 
provider at home and abroad in one click. 
20 
 
 
 
 
 
 
 
 
Crypto-miners can earn Universal Mobile Tokens (UMT), which are required in Bubbletone Blockchain to 
be used as a means of payment to pay fees for processing the transaction. UMT is a universal token to 
make a smart contract executable in Bubbletone Blockchain. When we connect new carriers and 
subscribers to the system, the number of transactions will grow. 
 
6. Characteristics of Bubbletone Blockchain 
 
Bubbletone Blockchain is planned to use Graphene Framework and Proof-of-Importance consensus. 
 
 
6.1. Bubbletone Blockchain will be developed using Graphene Framework 
 
Graphene is an Open Source C++ Engine developed in a very modular fashion, making it adaptable 
to many different uses. Our Blockchain will be developed on Graphene and can execute over 10,000 
transactions per second. 
 
The telecom industry needs hard, real-time transaction processing. Waiting over one minute for 
connection services is critical for the subscriber. 
21 
 
 
 
 
 
 
 
 
6.2. Development of the third-party apps 
We will have an open source platform and will invite developers to prepare new smart contracts for 
new partners. Also for Bubbletone, we will create a powerful platform for the development of third- 
party bots and small applications. 
After completion of the ICO, a Team & Community Development Fund will be created, which will amount 
to 78,000,000 UMT tokens (7.8% of all UMT tokens). 
Therefore, our requirements are: 
 
 
Intel i7, 8+ cores 
 64GB RAM 
 2xSSD 1Tb, RAID 1 (Mirror) 
 2x10Gb/s network interface. 
 
 
7. Business model of BubbleTone Blockchain 
Bubbletone Blockchain has two tokens due to following reasons: 
 
) The need to ensure stable prices of services for subscribers, and projected revenues for 
operators and service providers. For these purposes, the SDR token has a fixed rate pegged to 5 
major fiat currencies. 
b) The need to provide a link with the crypto currency market to give crypto-miners the 
opportunity to exchange revenues from transaction processing to fiat and crypto currency. 
22 
 
 
 
 
 
For these purposes, the Universal Mobile Token (UMT) has a floating rate inside the system 
based on internal rate and a limited amount. 
Our approximate indicative projections based on said observable market data and 
reasonable expectations on the Blockchain Ecosystem growth are as follows:

8. Technical specifications 
24 
 
 
 
 
 
8.1. High-level 
diagram 
 
A high-level diagram on 
how operators and 
subscribers interact with 
each other via Blockchain is 
shown below. The very 
important point is the great 
scalability of this business 
model because neither 
technical nor commercial 
integration between the 
operators are required 
Blockchain Telecom (BT) 
provides interoperability of 
mobile operators through 
the special smart- contracts 
(hereinafter - SSC), that are 
in fact a strictly 
predetermined finite 
automation, constructed 
from sequental 
transactions, that was put 
on  blockchain by users 
and operators. This goal is 
reached by consensus 
transaction processing, 
performed on blockchain 
nodes. Only transactions, 
corresponding to previous transactions, having right state, values and signatures of participating parties 
are valid. 
 
The function of SSC is to store client's funds, allow operators to charge client several times, and, finally, 
redistribute funds held by SSC between participating parties. These transactions offer services, open 
requests for service, charge clients and, finally, transfer payments to operator, performed the request, 
fee to operator, published original request, and change to client. 
 
Execution of SSC, validation of transactions and publication of the new blocks in BT is performed in a 
decentralized manner, on high-speed nodes, providing extremely high, stable and predictable rate of 
processing transactions. For the telecom industry, the quality of service in terms of transaction execution 
speed is not a wish, but absolutely necessary condition for the existence. So, for the implementation of 
the SSC, we consider only high-speed blockchain projects to ensure the finalization of the vast majority of 
transactions in a fraction of a second. 
 
BT uses special tokens - Universal Mobile Tokens (UMT) and SDR Tokens. The economic model of these 
tokens is described in detail in the "Business Model" section. Here we mean that the main goal of 
participating parties is a safe, effective (in terms of storage), and technically undeniable (excluding 
collusion between nodes) transmission of correct amounts of funds from one party to another. 
 
 
 
 
 
8.2. The general procedure 
25 
 
 
 
 
 
Operator, that provides service (hereinafter - "Assignee"), sends a so-called "Offer" transaction to BT. 
"Offer" transactions contain the information necessary for obtaining the service: price, amount of traffic, 
and other information, encrypted, if needed. These transactions are actually an operator's prices with 
info, needed to buy a service. 
 
Operator, representing a subscriber (hereinafter - "Issuer") selects from the fresh blockchain block an 
"offer" transaction, i.e. a specific service with specific parameters and cost. With this offer, Issuer 
initializes the SSC using transaction "Request", which indicates the Assignee, who must carry out 
request, and set the required parameters. "Request" transaction is linked to corresponding "Offer", by 
signing it, so, with "request" transaction Issuer starts transactions chain, that we call SSC. Also, 
"Request" transaction "freezes" some fixed amount of Issuer funds in SSC. These funds will be used as 
maximum amount of funds, that can be spent on Assignee' services. 
 
Then, Assignee, through the "charge" transaction, reserves amount of funds, needed to provide the 
service, and starts providing mobile services to the subscriber. it repeats this procedure several times, if 
needed, sequentally decreasing reserved funds, and increasing funds, destined to himself. All funds 
continue to stay frozen in SSC upon completion of SSC (by any cause, if everything was ok, if service 
failed, or SSC is expired by time-to-live). 
 
Then, Assignee, Issuer or Client through the transaction "Refund" completes the execution of SSC and 
funds are finally distributed between all participants. 
 
 
8.3. Detailed discussion of smart contract 
 
The basic algorithm can be represented by a graph of transitions of SSC states. Each edge of the graph - 
is a transaction, validated and related to the previous transaction with strictly defined type. For 
example, "charge" transaction will not be accepted by the network if the network does not have a 
previous transaction with type "request" or "charge" transaction cannot prove its acceptance by signing 
it. 
 
In the first version of the protocol, we consider only four different states of SSC - offer, request, charge, 
refund: 
 
Offer - a transaction that declares the service of a particular operator, its price, and other info about the 
service. The "offer" transaction can have no previous transactions, and the SSC uses it as an initializing 
transaction for the whole SSC transactions chain. 
 
Request - is the transaction following the "offer", placing information about the client and the 
operator that is invited to serve it. It transfers some "reserved" amount of funds from client to SSC, 
and now the only way to return them is send the "refund" transaction. Also, it contains the information 
necessary to provide the service. The transaction, in fact, places deposit and makes a "task" to 
operator-assignee in response to his "Offer". 
 
Charge - a transaction, following "Request" or previous "Charge". It fixes a certain part of service (billing 
step), which the operator-assignee has provided (or planning to provide). This transaction can be sent 
multiple times, until there are funds, allowed for charge, and all other conditions are met. But in all cases 
the transaction must certify previous transaction ("Charge" or "Request"), thereby transitively 
accepting "Offer" conditions 
 
Refund - a transaction which is carrying out the final allocation of funds. Called by any participant it 
stops the SSC, transferring funds to the participants in the amounts, corresponding to the charges 
provided. In the first version of the protocol there is a special flag, indicating that the refund is caused by 
bad, or non-working service. The number of such transactions, in relation to a particular operator, is a 
good metric for independent rating of mobile carriers. 
26 
 
 
 
 
 
Each transaction in this transactions chain, except the first "Offer", includes the signature of the previous 
transaction. Thus, each participant confirms the fact that he sees the correct processing of the history of 
SSC and agree with it. Otherwise, it sends to the network a transaction refund, returning a portion of its 
funds, and notifying the network about his complaint on quality of service of particular operator. 
 
The states (transactions) of SSC are presented in Yellow Pages called "Service Smart Contract states and 
transitions description" 
 
 
8.4. SSC side points and practical aspects 
 
We would like to see all the interactions between the operators of the transaction took place within BT. 
This will allow the network to be as robust and flexible as well as eliminate the need for direct 
integration between operators, that was a big technological problem for a long time because of very 
diverse equipment. 
 
Symmetric key exchange, organized within the SSC from first transaction is very useful for such kinds of 
interactions in BT, allowing parties to organize fast and secure communication channels, saving time 
and resources spent for extra challenge-response handshakes between operators' equipment. 
 
For example, when a subscriber wants to register in an operator's network, a mobile profile (including 
credential data) of this operator should be downloaded onto SIM card (or embedded SIM chip) over-the- 
air. The necessary symmetric keys can be obtained by both parties from "Offer", "Request" and "Charge" 
transactions. 
 
Downloading of mobile profiles is performed by Issuer onto its SIM-cards using one of the standards for 
the telecom industry: 
 Remote SIM Provisioning (https://www.gsma.com/rsp/2017/04/12/remote-sim-provisioning- 
works/) 
 Download information on the SIM-Map of SMS-channel in accordance with the GSM 03.48 "Security 
Mechanism for the SIM. The solution for safe mobile profile downloading and installing is already 
realized by our team, or Issuer can use solutions from other companies, but it's important that these 
solutions satisfy the standards above. 
 
8.5. BT Blockchain requirements 
 
The main requirements for BT is a guaranteed level of service. Stable transaction closure speed is 
critical, because otherwise the client will not be able to get the service she/he needs. It should be noted 
that at a stable transaction closing rate, we mean not only the average time of placing the transaction in 
a block, but also the problems of peak loads. Even in the case of a high average speed, a noticeable 
increase in processing time at peaks (for example, when a big operator publishes many service offers or 
charges), BT must continue to steadily serve customers. So, at the current stage we plan to use only 
highly available specialized servers responsible for their availability and performance. 
 
The job of the BT node is the validation of all new transactions, adding them to blocks and publishing 
blocks in the p2p network. Node checks the current transaction, searches for the previous one in the 
blockchain, checks the signatures and balances of the participants. The inclusion of a transaction in the 
block means that the node verified it, verified its authenticity, and guarantees the correctness of the 
data. Also, it is the node that receives the commission for placing the transaction in the block. 
Transaction validation, in fact, is actually executed by an SSC because all our logic, checking signatures, 
balances, transactions order really only makes one choice - is the transaction valid or not. 
So, the SSC is "hardcoded" in the node's validation algorithm and renews only with the node's software. 
 
The requirement for quality of service limits the range of available solutions for building BT. From the 
candidates for building high-speed blockchains with a controlled closing time of the transaction, we 
27 
 
 
 
 
 
selected engines based on the consensus of the Delegated Proof of Stake. They make it possible to assign 
high-performance servers as delegates, closing blocks at a predictable rate, and control the degree of 
decentralization. In future versions, the options for building a node hierarchy in BT are considered, 
allowing some transaction processing jobs to pass to client devices, which let them helping nodes. 
 
Also, a good candidate for the role of the main blockbuster BT are the engines that implement sidechains 
for large, decentralized blockchains - Bitcoin and Ethereum. We examine the Rootstock and Plasma 
engines to evaluate their suitability for our task. There is a big advantage in that they allow using of 
traditional BTC and ETH crypto currency in the system, greatly facilitating the fight against the volatility 
of the working token and are more convenient to use than the self-made tokens. 
 
Nevertheless, at this stage the most promising direction of development is the Graphene engine 
and solutions based on it (Bitshares, Steemit, Golos). This engine already works in  the  
production environment, it is constantly developing, and,  most  importantly for us, it provides  
the following important functions: 
 
Add / remove delegates (Super Nodes) 
 
p2p network for publishing transactions and blocks 
 
implementation of "transfer" and other exchange functions 
 
account management and many functions to operate with accounts 
 
excellent performance due to implementation in C ++ 
 
many types of transactions and the ability to create and modify our own types 
* 
The implementation of the SSC in the Ethereum network is also considered as a prototype in 
order to present a solution to the experts and the community. 
 
One of the implementation problems is the update of the software on the nodes. SSC implies further 
development, and, as realists, we know that the protocol will require changes, at least necessary to add 
the data to provide new types of services. Changing the logic of transactions validation can easily take 
out an outdated node, so we plan to make protocol changes that are strictly compatible with previous 
versions. The fact that delegate nodes belong to operators, who have a real economic incentive to keep 
the code up-to-date, is an additional advantage. 
 
Including new operators in BT is also a problem. To provide telecom services, the operator must 
undergo an offline validation procedure, have a license and title documents. This, on the one hand, 
protects the network from bad players, and on the other hand it obstructs the operational management 
of the network. We plan to resolve this issue with the help of a functionality that will force operators to 
participate in the election of new delegates. Those participants who did not participate in the procedure 
of consensus adding / excluding operators for a long time will be penalized by a rating downgrade and 
exclusion from consensus. 
 
Decentralization of BT is not an easy matter. From the client's point of view, BT is not decentralized, it's 
just a convenient service. From the operator's point of view, BT is decentralized, because nodes are 
equal and are not controlled by any entity. We do not see a contradiction here because the internal 
interaction of operators among themselves is not a problem of the client, who in general does not care 
how they get the service. At the same time, it is important for operators to know that each node is 
independent, and transactions in BT are technically undeniable. 
 
A separate discussion is the possibility of information attacks on the BT. The implementation of the 
SSC requires many searches in the blockchain to find the previous transaction in the chain 
belonging to the same SSC. For example, after seeing the "charge" transaction published by the 
client, the node must find the corresponding "request" transaction. If we do not limit this process, 
we will have to look through the whole blockchain, not part of it. To limit the number of blocks 
viewed, each transition of the SSC from state to state must have a restrictive period (with the 
exception of the "refund" transaction). In this case, knowing that "charge" cannot persist longer 
than Tmax seconds from the previous transaction, we can restrict the search to blocks belonging 
only to the last interval of Tmax seconds. Unfortunately, this way you cannot restrict the transaction 
refund - any participant should be able to return the funds belonging to them, regardless of when 
they were placed in the BT.

8.6. Digital Identity Management for users of Bubbletone Blockchain 
Bubbletone Blockchain is a global project with users from any location in the world capable of accessing and paying 
for the telecom and non-telecom services. With this in mind, the task is to ensure user identification from the part of 
both mobile operators and value-added service providers wherever they are located in the world. 
 
The personal data that the user transferred to their home operator is considered as the basis for user identification on 
the Bubbletone Blockchain platform. To ensure the safety of the users' personal data while at the same time enabling a 
universal means of authentication by mobile network operators and service providers globally, we utilize the users' 
digital identities. 
Using modern and standardized cryptography with peer-to-peer encryption, the data is safely transferred from the 
user to his home operator to create a digital footprint. It is then stored on the blockchain as a hash of the data, 
followed by a status indicating whether the data was certified. 
 
While transacting with the Bubbletone Blockchain to access services, the users give their consent to be 
authenticated by transferring their individual identifier to the operator. After the data is decrypted on the receiving 
side, it can create a hash of the data and compare it to the hash obtained from the blockchain, in order to make sure 
the provided data is valid and certified. 
 
For digital identification of users on the Bubbletone Blockchain, we plan using software developed by the 
company ShoCard. They are a proven worldwide provider of advanced solutions for industries where secure, 
swift and convenient digital identity management is critical. We have achieved good integration results while 
testing solutions by ShoCard on our systems.

11. Our partners 
 
Initially we're creating a community of small and medium-sized mobile operators that are looking for 
new services for their subscribers, such as global mobile coverage and value-added services, as well as 
new revenue streams on inbound tourists, Identity-as-a-Service and Voice-over-IP calls. 
 
10+ operators with 20+M subscribers are ready for Proof of Concept (PoC) of the "Blockchain in 
Telecom" solution. 
 
We have signed an agreement with world-famous English-learning service called "Lingualeo" to be 
connected to the Blockchain platform. It allows accepting SDR tokens to pay for language services as 
well as expanding sales channels via mobile operators. 
We have become full member of the Crypto Valley Association. It is one of the world's leading 
ecosystems established to develop crypto, blockchain and distributed ledger technologies. 
 
We have signed partnership agreement with ShoCard Inc., the premier provider of blockchain-based 
identity verification. 
 
12. Competitors 
 
 Roaming hubs are intermediators between mobile operators to provide interconnectivity with use of 
roaming technology. This technology is very complex and expensive, especially for small and 
medium operators. As a result, it takes 2  3 years and 10+ million USD to launch global coverage 
offer for subscribers. "Blockchain in Telecom" resolves this issue within weeks without investments 
in infrastructure. 
 Project Fi powered by Google offers tariff plan with low rates (about $10 per GB) in 135 countries. 
But it's workable on Google smartphones only, requires monthly subscription fee ($20 a month) and 
doesn't support LTE quality in most of these countries. Also, it's a proprietary solution which 
couldn't be implemented by third-party operators. 
 Apple SIM is workable on some iPad's only, has rather high rates (3  5 times higher comparing to local 
prices) in most of supported countries. This solution is proprietary too. 
 
 
13. Terms of tokens distribution 
The token is priced in Ether crypto currency. 
 
13 .1. Private Placement 
 
Private pre-sale terms and conditions are available upon request. 
 
 
13.2. Pre-ICO and ICO 
 
Tokens at these stages will be available as follows:

All tokens unsold during crowdsale will be burned. 
Funds received from the sale of UMT tokens are placed in escrow and are transferred to the 
Bubbletone according to the roadmap after end of ICO and as users receive their tokens.  
 
13.3. Tokens distribution at Pre-ICO and ICO 
 
We are planning to withdraw from circulation the tokens from the Network Development Fund (NDF) 
for depositing on accounts of service-providers for generating transactions. All income generated from 
them should go back to the NDF 
 
The Founders fund is subject to vesting at 7% per month. 
 
We are planning to use tokens from the Team & Community Development Fund (TCDF) as as 
reward for several purposes: 
 
 For ICO promotion 
 For distributing tokens within 24 months of platform start to pay off the node ownership costs while 
there are not enough private Super nodes on the platform 
 For providing bonuses, but no more than 7-10% per month, to node-owners to ensure the nodes 
productivity. 
 To motivate new team members, business and legal advisors, developers and subcontractors. 
 To organize community growth in all means possible. 
 To prevent a deadlock situation, when there may not be enough UMT to perform the transactions.

13 .4. Technology and security 
 
The platform we have chosen for our crowdsale is Ethereum. Smart contracts for tokens and crowdsale 
will be written in the Solidity language. The provisions outlined in this document will be guaranteed in 
smart contracts with cryptographic reliability. The collected Ether will be stored in a separate contract 1 
that provides an automatic return of funds to contributors in case of the ICO failure. 
 
Smart contract management and withdrawal of funds will both be protected by multiple signature. 
 
In crowdsale contracts, there will be a fallback mode (pause), which will automatically turn on if a leak 
of funds is detected, and can be activated by the owners in any unforeseen circumstances. This regime 
is designed to protect the collected funds and prevent the receipt of new funds in case of threats. 
 
Before the deploy to the Ethereum main network, the smart contracts code will be fully covered by unit 
tests and tested in the test network. The contract code will be published on Github, and the bytecode 
will be verified in the Etherscan.io service.
